FIG. 1 is a diagram illustrating a constitution of an image forming apparatus 1 (scanner).

The image forming apparatus 1 is an MFP (Multi-Function Peripheral) which has a copy function, a printing function, a scanning function, a FAX function, an Email sending function and the like. The image forming apparatus 1 comprises a first reading section 2, a second reading section 3, an image forming section 4, a communication section 5, a controller 6, a HDD 7 (Hard Disk Drive), a display section 81 and an operation section 82.

FIG. 2 is a diagram illustrating the first reading section 2 and the second reading section 3.

The first reading section 2 and the second reading section 3 are arranged inside an ADF 9 (Auto Document Feeder).

The ADF 9 feeds a sheet from a sheet feeding tray 91 to a conveyance path 92 inside the ADF 9. The ADF 9 discharges the sheet to a sheet discharging tray 93 after images on double sides of the sheet are read by the first reading section 2 and the second reading section 3.

A space D between the first reading section 2 and the second reading section 3 in the conveyance direction of the sheet is shorter than a length of the sheet in the conveyance direction. The sheet which specifies a maximum space D is a sheet having the smallest size among the sheets subjected to a reading operation. For example, the maximum space D is 140 mm which is a length in the conveyance direction of a sheet having a size of an STMT (Statement Half Letter).

As the space D between the first reading section 2 and the second reading section 3 in the conveyance direction is shorter than the length of the sheet in the conveyance direction, the first reading section 2 and the second reading section 3 can read double sides of the sheet simultaneously. Hereinafter, in a case of reading double sides of the sheet with the first reading section 2 and the second reading section 3, it is usually described that double sides of the sheet are read by the first reading section 2 and the second reading section 3 simultaneously.

The first reading section 2 reads a front surface (a first surface) of the sheet on the sheet feeding tray 91. The front surface of the sheet refers to the upper surface of the sheet on the sheet feeding tray 91. The rear surface of the sheet refers to the lower surface of the sheet on the sheet feeding tray 91.

The second reading section 3 reads the rear surface (a second surface) of the sheet on the sheet feeding tray 91.

The first reading section 2 and the second reading section 3 may be a CIS (Contact Image Sensor) or a CCD (Charge Coupled Device).

Return to FIG. 1, the image forming section 4 transfers an image on the photoconductive drum onto the sheet with a toner. The image forming system of the image forming section 4 may be an inkjet head system or thermal system in addition to an electrophotographic system.

The communication section 5 is connected with a network in a wired manner or wireless manner. The communication section 5 includes, for example, an NIC (Network Interface Card) to communicate with a client terminal such as a PC via the network.

The controller 6 controls the whole of the image forming apparatus 1.

The controller 6 includes a processor 61 and a memory 62.

The processor 61 reads programs stored in the memory 62 to execute various processing.

The HDD 7 stores reading images of the sheet read by the first reading section 2 and the second reading section 3.

The display section 81 displays setting information and operation status of the image forming apparatus 1, login information and a notification to a user.

The operation section 82 is a touch panel or buttons and keys. The operation section 82 receives an input of the user and an instruction of a functional operation of the image forming apparatus 1 such as a printing instruction and the like.

FIG. 3 is a flowchart illustrating procedures of a reading processing carried out by the controller 6.
